REED-PROTECTOR MECHANISM FOR FAST REED-LOOMS.

SPECIFICATION forming part of Letters Patent No. 416,167, dated. December 3, 1889.

Application filed February 18, 1889. fierial No. 300,382. (No model.)

To all whom it may concern:

Be it known that I, JACOB JUCKER, a subject of the Queen of Great Britain, residing at .Manchester, in the county of Lancaster, in

. is a specification,

My invention relates to reed protector mechanisms for fast reed-looms.

* The object of my invention is to provide an improved combination of elements for relieving the shuttle during the picking from the pressure of the springs actuating the stop-rod, in combination with a previously-known device for relieving the shuttle from the press ure of the said springs while it runs into the box, the specific object of my invention being not only to relieve the shuttle from pressure during the picking and running in, but also entirely to prevent the vibration of the stop-rod and levers attached to the same while the Weaving proceeds, and thereby to render the action of the reed-protector motion (in case the shuttle sticks in the shed) more certain.

As heretofore constructed the catches in the ordinary reed-protector motions frequently miss the stop or frog, when the motion is set into operation, by the absence of the shuttle from its box, in consequence of the vibrations of the catches caused by their inertia in quick-running looms, and catch the frog and stop the loom only at the next heat. It strong springs for actuating the stop-rod are used to remedy this defect, the pressure on the shuttle and the friction of the latter on the back swell is increased, so that heavier picks are required, and the consumption of power, the wear and tear, and the vibrations of the loom are increased. The devices hitherto used for relieving the shuttle during the pick contain separately swinging or guided parts, which, during each revolution of the crank, make a vibratory or reciprocating movement under spring-pressure, therefore again increasing the driving-power required and leading to a rapid Wear of their bearings or guides and fatigue of the springs, in consequence of which they do not act with certainty in quick-rum ning looms. My improved relief-motion does not contain any parts separately supported in bearings or sliding in guides; butonlya stoprod supported in the usual way, and, acting in combination with a motion for relieving the shuttle during the running in, it entirely prevents the ordinary vibrating motion of the stop-rod, so that the bearings for the latter are not worn, nor are the springs actuating said stop-rod fatigued.

Referring to the drawings appended here unto, Figure 1 shows a front view, and Fig. 2 a side view, of the end part of a lathe and 100m frame, with my improvements applied thereto. Figs. 3, l, 5, and 6 are sectional views on an enlarged scale, showing the invention in different phases of operation.

In the different figures, (t denotes the loom side frame; 17, the lathe -bottom; 0, a shuttlebox; 0, (removed in Fig. 1,) the front of the same; (1, a lathe-sword; e, the rocking shaft or rail on which the lathe is mounted; f, a hearing for the same; g, the stop-rod; 7b, a bearing for the same; i, a crank 011 the crank-shaft of the loom, and 7a a crank-arm. These parts are arranged as usual.

The ends of the stop-rod g are flattened and the bent fingers m are bolted to the same. The end of each of the said fingers is broadened into a square plate m which passes through an opening in the back-swell n, so that the latter can move independently from the stop-rod. Opposite to one or both the swords d a lug p is forged on the stop-rod, to

which a curved arm 1' is fixed. On the under side of the crank-arm k a second curved arm 5 is fixed. The under side of the arm 7.; at the front end and the upper side of the arm '1' are both curved to an arc of a circle struck catch Z down, so that it encounters the nose.

reaches about the position marked y.

The shuttle is picked while the crank moves a from its foremost position to 3 through the lower part of its rotation, and the shuttle is consequently relieved from the pressure of the finger m and spring Z. This device for relievingthe shuttle during the pick when used in combination with apreviouslyknown device for relieving the shuttle during its running into the box entirely prevents the oscillation of the stop-rod and parts attached to it, which occurs with ordinary motions and produces the difficulties hereinbefore pointed out. Said ordinary device consists in forming the back part of the catch-blocks or frogs o with raised parts or projections o, curved to a radius struck from the center of the rocking-rail bearings f, and of such height that when the catches Z ride on these parts 0 the finger m is just raised off the shuttle. The catches Z ride on the parts 0' while the lathe is near to its backward position, Fig. 4, in which the running in of the shuttle takes place. During the backward beat of the lathe, after beating up, the stop-rod is first held by the arms r and s sliding on each other, Fig. 3. When these become disengaged, the catches Z have arrived at the parts 0 of the frogs 0, and hold the stop-rod in the same position. WVhen the forward beat commences, the catchesZ at first slide on the parts 0' till the shuttle has entered the box, and are then held up by the shuttle itself till the arms 0' and s have become engaged again. The stop-rod thus makes no oscillations while weaving, and only moves when the shuttle misses its box, Fig. 5, whereby the wear of the stop-rod bearings is obviated, the springs Z are not fatigued, and the use of springs of any strength and a quicker speed of the loom are rendered possible.

I claim as my invention- 1. The combination, with a crank-arm k, a stop-rod g, of spring Z, actuating said stoprod, finger m, curved arm 7", and catch Z, attached to said stop-rod, curved arm 8, attached to the crank-arm, and the frog provided with curved part 0, all constructed as and for the purpose herein specified.

2. The combination of a crank-arm k, a

stop-rod g, a curved arm 7*, connected thereto, and a curved arm 8, engaging with the firstnamed rod 7' and attached to the crank-arm 7c.

3. The combination of a crank-arm 7a, a stop-rod g, flattened at th eend, bent finger m, bolted to the same, the end of said finger bein g broadened into a square plate m, a backswell n, containing an opening through which passes the said square plate m alathe-sword (Z, a lug p on the said stop-rod opposite the lathe-sword (Z, a curved arm 9', applied to the stop-rod, and a second arm 5, applied to the under side of the crank-arm 7c, the under side of the arm .9 and the front end and upper side of the arm 0' being both curved to an arc of a circle struck with the same radius from the center of the bolt 2, connecting the crank-arm Z; and lathe sword d, and both arms being rounded at the ends.
